Steam the dumplings until the outside of the dumpling becomes clear to reveal the vegetables inside.

Remove the steamed dumplings (try not to let them cool) and dip in a dish containing a mix of vinegar and
ra-yu (red-pepper oil). Another alternative is to dip the dumpling in a dish containing a mix of mustard and soy-sauce.

Hint:

Deepfry the dumplings but make sure to remove all the excess oil with kitchen paper.
